What is the effect of load on the efficiencY of an induction motor?

Stator Voltage Control of an Induction Motor using PWM The objective: The objective of this experiment is to present the voltage control of induction motor Discussion: 1. Briefly, discuss the starter voltage of induction motor speed control? 2. What are the disadvantages of this method?

What is the reason of the high starting current in the 3-phase induction motor? Explain in short.

22. A) Why is the power factor of a lightly loaded 3-phase squirrel-cage induction motor very low? a) most of the power supplied to the motor at light loads is magnetization or inductive power b) most of the power supplied to the motor at light loads is resistive power c) most of the power supplied to the motor at light loads is capacitive power d) none of the above B) What happens to the power factor as load is increased on the motor? a) the power factor increases b) the power factor deceases c) remains the same
